Travis Steel is a well-known manufacturer and supplier located in Canberra, Australia, specializing in high-performance **Alloy Steel WP91 Pipe Fittings**. Renowned for their exceptional quality and precision, the company produces fittings that can handle extreme pressure and temperature conditions. Their product lineup includes elbows, tees, reducers, caps, and stub ends, all crafted to meet international standards like ASME and ASTM. With a strong commitment to innovation, durability, and customer satisfaction, Travis Steel guarantees that each fitting offers outstanding mechanical strength, corrosion resistance, and reliability for critical industrial and power generation applications.
Alloy Steel WP91 Pipe Fittings consist mostly of Chromium (Cr), Molybdenum (Mo), and Carbon (C), with a usual composition of 9% Chromium and 1% Molybdenum, which gives them high strength, toughness, and resistance to heat and corrosion. Their mechanical properties are a very good tensile strength of usually 585 MPa, and a yield strength of 415 MPa. They also have high creep strength and thermal fatigue resistance, which makes them suitable for power plants and similar applications involving high pressure and high temperature. They have a hardness level of 190 to 250 HB, providing durability and long service life.
